EMBROIDERY-HOOP.

To all 10h-0m t may concern.'

Be it known that I, L'Ewis Giens, a citizen of the United States,residing in Canton, Chio, have invented certain Improvements inEinbroidery-l-loops, of which the following is a specification.

My invention relates to that class of em broidery hoops in which theouter hoop is expansible and contractible in order to permit of theready application, removal or readjustment of the material for whoseconlinement the hoops are intended, one object of my invention being toinsure the hrm retention of such material, while permitting readyadjustment of the same.

Another object is to so construct the expansible and contractible hoopas to render unnecessary the overlapping of the ends of the same and theconsequent `tapering or feather edging of one of said ends in order toavoid an abrupt shoulder on the inner face of the hoop, my improved hoophaving squared ends which, if desired, may be caused to abut when thehoop is contracted.

A further object of my invention'is to laterally retain the ends of thehoop independently of the adjusting device, the only function of thelatter being to spread or contract the hoop, and a still further objectis to provide an adjusting device which, while lightin weight, is strongand compact, and will securely retain the hoop when the latter iscontracted.

These objects I attain in theV manner hereinafter set forth, referencebeing had to the accompanying drawings, in which- Figure 1 is aperspective view of a pair of embroidery hoops, the outer of which isequipped with an expanding and contracting device in accordance with myinvention; Fig. 2 is a perspectivev view of the inner faces of themeeting ends of the outer hoop showing the same in the expandedcondition; Fig. 3 is an enlarged horizontal section showing the outerhoop in the contractedcondition; Fig. 4 is a similar view with the hoopin the expanded condition; Fig. 5 is a transverse section on the linea-f.z, Fig. 3; Fig. 6 is a transverse section on the line 5 5, Fig. 4;Fig. 7 is a perspective view of one end of the hoop;l

of the adjusting device employed in conneet-ion with the opposite endsof the hoop; Fig. lO is a view similar to Fig. 3, but illus trating amodification of my invention, and Fig. 1l is a sectional viewillustrating another modification.

ln Fig. 1 of the drawing, l represents the inner hoop and 2 the outerhoop, said hoops being composed of wood, vulcanized fiber,

or other available material, and the inner hoop being a plain orcontinuous hoop preferablyl provided, on its outer face, with a facingor covering 3 of felt or textile material for the purpose of insuring anelastic grip upon the material which is to be clamped between the twohoops, although, if desired, this layer of felt or textile material maybe applied to the inner face of the outer hoop or both hoops ma)7 bethus provided, if desired. The outer hoop 2 is split in order that itmay be expanded to permit of ready introduction between the hoops of thematerial to be confined thereby and then contracted upon said materialin order to effect the secure clamping of the same between the hoops.

When the felt or textile facing is employed in connection with either orboth of a pair of hoops, one of which is expansible, the material to beheld by the hoops is, when the expansible hoop is contracted, confinedmore firmly in position than when both hoops are continuous, while whenthe hoop is expanded, free movement of the material is permitted andadjustment of the same in respect to the hoops can be readily effected.The meeting ends of the outer hoop are square, that is to say they areat a right angle to the inner and outer faces of the hoop, in order topreserve the full strength of the material up tothe end of the hoop,whereas if one end of the hoop overlaps the other, the inner overlappingend must be tapered or feather edged in order to prevent the formationof an abrupt shoulder on the inner face of the hoop, thereby not onlyweakening one end of the hoop but forming an objectionable thin edge onthe same which is liable to be broken in use.

The meeting ends of the hoop may also be square in respect to the topand bottom edges of the same, although it is preferable V vide adiagonal joint as shown in Fig. 2,

and thereby prevent the formation in the outer hoop, when the same isexpanded, of a vertical gap into which the material to be confinedbetween the hoops might enter and thus prevent the proper contraction ofsaid outer hoop.

Each end of the hoop is provided with a metallic tip plate, that at oneend of the hoop being represented at 4 and that at the other end of thehoop at 5, these tip plates being secured to the wood or other materialof which the hoop is composed by means of pins, rivets, or othersuitable fastenings 6. The tip plate 4 has a thickened end 7 in which isformed a slot 9, elongated vertically, and the tip plate y5 has a pocket10, formed by bending or folding over toward each other wings 11 forminga part of said tip plate 5 as shown in Fig. 8.

The thickened end 7 of the plate 4 is fitted to the pocket 10, but canslide freely therein, the ends of the hoop being thereby retainedlaterally, so that, irrespective of its function of expansion andcontraction, the hoop possesses all of the qualities of a solid hoop.Mounted on the pocket 10 of the tip plate 5 is a recessed disk 12provided, by preference, with a knurled or milled edge whereby it can bereadily turned by the fingers, this disk having a hollow hub 13 whichpasses through the back member of the pocket 10 and is expanded in anopening therein so as to laterally confine the disk 12 to the pocket.Secured to or formed integral with the disk 12, or its hub 13, are disks14 and 15, the disk 14 being concentric with the axis of the hub 13 andadapted to turn freely in an opening 16 in the outer member of thepocket 10 and the disk 15 being eccentric in respect to the axis of thehub 13 and adapted to the slot 9 in the thickened head 7 of t-he tipplate 4, as shown in Figs. 3, 4, 5 and 6.

When the disk 12 is turned so that the eccentric disk 15 occupies theposition shown in Figs. 3 and 5, the hoop 2 will be fully contracted andwhen the parts are adjusted to the position shown in Figs. 4 and 6, thehoop 2 will be fully expanded. When in either of t-hese extremepositions the eccentric disk 15 is seated in the bottom of the slot 9,consequently, when the disk 12 is turned so as to open the hoop, itsmovement is arrested when the hoop is fully exi panded, and in likemanner, when t-he disk is turned so as to close the hoop, its movementis arrested when the hoop is fully closed. By this means accidentalspreading of the hoop after it has once been contracted, or accidentaltightening of the hoop after it has once been expanded, is prevented, assuch change in the condition of the hoop requires a reversal in thedirection of movement of the operating disk 12 and said reversal impliesattention on the part of t-he operator, whereas, if the disk 12 was freeto make a complete turn, the hoop would be liable to accidentalspreading after being contracted or to accidental contraction afterbeing expanded.

As shown in Figs. 1, 2 and 8, the tip plates 4 and 5 are applied to theouter face of the hoop but they can, if desired, be applied to theinnerface, an instance of this construe# tion being shown in Fig. 10,and the pivot hub of the disk 12, instead of being integral therewith,may be a separate pin secured to the disk as shown at 13a in Fig. 10 orsaid pivot hub may be in the form of an eyelet as shown at 13h in Fig.11, the disks 12, 14 and 15 being secured together and free to turn onthis eyelet or these disks being secured to the eyelet which is free toturn in its bearing in the Vinner member of the pocket 10.
